how many electrons will chlorine need to gain or lose to be left with a full outer shell of valence electrons? gain 1 lose 2 gain 3 lose 4 gain 5 lose 6 gain 7 lose 8
Answer
Explanation:
Step1: Identify chlorine's valence electrons
Chlorine has 7 valence electrons.
Step2: Determine full - shell requirement
A full outer shell of valence electrons has 8 electrons for most elements.
Step3: Calculate electron change
To get 8 valence electrons, it needs to gain (8 - 7=1) electron.
Answer:
A. gain 1
